"I contracted Robert in April 2017 ,to seal ,leak test,and initial check for startup.He quoted me 300.00 for each unit.I though it was a high price but I agreed as a tech would be out the following day.They arrived on schedule but unprepared .The tech did not have any tubing wrenches ,only large crescent wrenches,a poor choice for small copper fittings.I didn't have any either but loaned him my full set of open/box wrenches.He proceeded to tighten all connections an test them.He could not get his Freon leak detector to work properly,kept alarming when not near any connections . I made up a spray bottle of soapy water for to check for leaks.This service lasted about 4hrs.Everything looked good and seemed to work fine.So I re-insulated all connections and re-installed duct covers.I was 7 months in renovation .In January of 2018 I was ready to paint but the temp inside the house was to cold.I turned on both systems heat pumps for first time since start-up, and nothing happened .No heat or cool.I called Robert and told him of the failure.He sent the same tech out again my wrenches my spray bottle.I had to undo the tube duct and insulation for 6 air handlers with 10 connections. Three hours latter ,240.00 labor and 280.00 for Freon. The service tech tells me everything is sealed an ready to run. I ran the units for two days for painting. I turned both units off while I completed sheet rock and floor finishing.On June 18,2018 I had furniture movers in and the house was hot so I turned cooling on for first time since last repaired and nothing happened ,no cooling.I called Robert to please do the job he had been paid twice for,to seal this system with no leaks.

We will perform any type of residential construction, repair & remodeling services in the lower Florida Keys.

"2020 has passed and we couldn't be happier with our completed first floor project, thanks to Jim Rutherford Construction. Jim was willing to tackle what other local well known contractors were either unwilling to consider or bid so high as to be unaffordable. Our project proved to be a technical challenge from the onset, raise the ground floor by almost a foot of concrete, completely rebuild the first floor by installing 3 impact French doors, 3 impact doors and 4 impact windows, cut off support an internal staircase including modifying framing around a dumbwaiter, reframe and replace every exterior wall from 4' down. Plus an added surprise rebuilding and repairing 45' of a heavily spalled concrete tie-beam in less than a week. We're still amazed at how quickly and confidently Jim set about taking on the project, he seemed to have it figured out before we even committed to getting started. He knew just right carpenters and subs to assign the work to. Once they began, they never stopped till the project was completed. Workmanship was outstanding, inspections were a breeze. I commend Jim and his crew for the quality of work and attention to detail, no shortcuts taken, stainless hardware/fasteners throughout and only pressure treated lumber. Add them all up and we have a completely new remodeled permitted downstairs ready to withstand the elements. It is without hesitation we'd recommend Jim Rutherford Construction for any project or home construction. Professional, polite and a pleasure to do business with."

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
